HESI A2 Vocabulary 2023 Questions
Question 1 of 5
Select the meaning of the word 'undulate' in the sentence: 'Each shiver made his muscles undulate beneath his skin.'
Correct Answer: A
Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.
Question 2 of 5
If a patient is especially obdurate, she is ___________.
Correct Answer: B
Rationale: The correct answer is B: quite stubborn. "Obdurate" means stubborn or refusing to change one's opinion or course of action. Therefore, a patient who is especially obdurate would be characterized as being quite stubborn. The other choices are incorrect because being obdurate does not necessarily have any direct correlation with being very large (A), easily upset (C), or ready to go home (D). It specifically refers to being stubborn or resistant to change, making choice B the most fitting description.
Question 3 of 5
Which bone is shorter in the forearm?
Correct Answer: B
Rationale: The correct answer is B: Radius. In the forearm, the radius is shorter than the ulna. The radius is located on the same side as the thumb, while the ulna is on the side of the pinky finger. The humerus is the upper arm bone, the scapula is the shoulder blade, and the fibula is a bone in the lower leg. So, the radius is the only bone among the choices that is actually located in the forearm and is shorter than its counterpart, the ulna.
Question 4 of 5
Which word describes a screen or filter?
Correct Answer: A
Rationale: The correct answer is A: Permeable. Permeable describes a screen or filter because it allows substances to pass through. Screens and filters are designed to allow certain particles or substances to flow through while blocking others. Choice B, Incendiary, is incorrect as it means causing fires. Choice C, Exuding, is incorrect as it means to discharge or emit. Choice D, Resilient, is incorrect as it means able to withstand or recover from difficult conditions. The key in this question is understanding the function of a screen or filter, which is to permit the passage of some substances while blocking others, making the term "permeable" the most appropriate choice.
Question 5 of 5
Select the meaning of the word 'amalgamate' in the sentence: 'If the companies amalgamate, some employees may lose their jobs.'
Correct Answer: C
Rationale: The correct answer is C: Merge. In the given sentence, 'amalgamate' is used in the context of two or more companies coming together to form a single entity. The word 'amalgamate' means to combine or unite. Therefore, in this sentence, if the companies 'amalgamate,' it implies that they are merging. Explanation for other choices: A: Disband - This means to break up or dissolve, which is the opposite of merging. B: Move - This refers to changing physical location and is unrelated to the context of companies merging. D: Regroup - This means to reassemble or reorganize, which is different from merging into a single entity.
